I've been invoking a javasript method from an applet using the
netscape.javascript.JSObject class.
All was working fine till I upgraded my JRE from 1.4.0 to 1.5
Now the method JSobject.getWindow(this) is returning an exception:
netscape.javascript.JSException
The javascript fails to call an embeded applet's function. In the javascript
console, it shows "Error XXXX is not a function". Following are some parts of my code.
if(parent.document.cpmApplet){
parent.document.getElementById('cpmApplet').refreshCPMApplet();
}
if(parent.BottomIframe.document.resultApplet){
parent.BottomIframe.document.getElementById('resultApplet').refreshTableApplet ();
}
Here parent.document.cpmApplet and parent.BottomIframe.document.resultApplet are valid since I loaded both the applets with the same name using <APPLET> tag for Netscape/Mozilla and OBJECT tag for Windows.
The issue is with Netscape and Mozilla on Unix platforms only. I would appreciate if anyone could help me to solve this.
We have an applet that has to support the SUN VMs as well as the MS VM.
The applet receives updates from a server (via tcp or http) and wraps them
up as objects and passes them using the JSObject scripting context to a
javascript function.
This function takes the object and reads the properties and updates a
screen.
All seems simple stuff. The problem is that the MS JVM runs like a rocket,
but the sun vm seems to max out our processor and also takes ages to process
anything.
I have tried logging from the console using debug level 5, and it shows a
lot of back and forth between the applet and the javascript when accessing
methods on the object passed.
Seeing that as a possible problem, I now pass a delimited string to the
front end, and then convert that into an update message purely in javascript
so there is only one hit to the applet per message.
I am still seeing a massive difference between the sun and ms VMs.
Has anyone ever come across this, and is there anything I can do to help
flatten out this performance?
I'm not actually sure that this issue was developed as I upgraded to jQuery 1.5, but it was very much around that time. I packaged my testcase and attatched it to the post. The fallowing error is caught in the JavaScript console when the Öppna Alla button is pressed on the site:

I have on a html page an applet. A javascript function call one function of
this applet. It works with IE but not with Mozilla or Netscape. I obtain
the following error on the java-plugin consol:
sun.plugin.liveconnect.OriginNotAllowedException: Javascript is not form the
same origin as je java code ...
This is my html code:
<script language="Javascript">
<!--
function askServerCmd()
{
return document.AppReaderLink.askServerCmd();
}
//-->
</script>
<applet CODE =" AppReaderLink.class"
codebase="."
ARCHIVE ="appredl.jar"
WIDTH =" 130"
HEIGHT =" 70"
NAME =" AppReaderLink"[color=blue]

I tri with jre 1.4.1_05 and jre 1.4.2_02 and I obtain the same thing.
What I have to do?
How do I display a message applet is loading when a applet is getting
loaded. Without using Mediatracker.I want the message to be provided as
PARAM NAME.
let's me explains my long problem:
I'm doing an intranet with a media part. So im must be able to upload files on
a ftp server AND have a record of informations about this file and meta date in
a MySQL database, shown in a php page.
So the first thing i was doing was:
1/ * A HTML Form, with a <input type="file"> which was uploading the file to
the web server. And then, in the next action-php-page, using ftp functions from
php to upload to the ftp server. But this make upload the file 2 times, which
slow, and the user can't do anythig except waiting in front of a blanck loading
page.
=> no way
(BTW, the site admin refuse that the ftp server and the web server to be the
same computer)
So i tried something else:
2/ * A HTML form, the user enter meta data about the media, click next, and
then, a php page which loads a java applet an pass informations to it (by param
tags).
The applet have a browse button, and a go button, which start the transfert
(JDK 1.4.1) trough the URLConnection. The file is uploaded once, and there is a
progress bar, which is wonderful.
But now, i need the src_file information wich is the java applet. So i have two
options:
A/ I make a post to the webserver from the applet. But i'm using session
identification (needed for tracing users actions) and i'm gonna use SSL in less
than one month, so i think it would be complicated.
B/ I export the information from the java applet to javascript, and then to
HTML hidden field, so that the user can submit the full-hidden-filled form. But
i can't make LiveConnect works.
i'm under Mac OS X 10.2 (jaguar) so i need to make work LiveConnect on both
Safari 1.0 (v85.6), mozilla 1.5, and Mac OS IE (5.2).
Does anyone know how you can test if an applet's method exists before you try and call it?
for example, if you don't have a JRE installed on your computer and try and access an applet method it shoots out a javascript error at you. I want to be able to test if the applet is operational basically before I try and use any of its methods.
I call methods in a Java applet with javascript code like this:
document.myApplet.methodName();
This works great when the applet has loaded (the JVM has started and dowloaded all the jars) but it fails if the applet hasn't loaded yet, at which point it gives an error:
Quote:
Error: Object doesn't support this property or method
Is there a way to determine that the applet is loaded or not so that I can use it in an if statement? For instance, like so:
Code:
if (isAppletLoaded()) {
document.myApplet.methodName();
}
I tried
Code:
document.myApplet == null
but that didn't work.
I am looking at a client’s site that has a scrolling text bar at the bottom of the page for latest news. I have been asked to recommend whether they keep the scrolling text as a java applet or whether they make it dhtml with Javascript to make it scroll.
To be honest, I’m not sure whether there really is an important difference, in terms of download time, likelihood of working (if client browsers are better enabled for one verses the other), or whether there are any other reasons one should be used over the other.
Here's my code:
// Lab09GRFX04st.java
// This is the student, starting file for the Lab09GRFX04st assignment.
// The Lab09 practice and graded assignment is open ended.
// No code will be provided in the student, starting file.
[code]....
It compiles; however, once I switch to the HTML window and try to run it, a screen appears and the status bar is giving me the "Start: applet not initialized error." Here's my HTML code:
<APPLET CODE = "Lab09GRFX04st.class" WIDTH=1000 HEIGHT=650>
</APPLET>
I am trying to call a PageMethod and it is failing. I am trying to get the error message but I am not sure how to display it (I am trying to use the alert() function). I have tried alert(result) but all that is displayed is object [Object]. I have tried result.d, but that returns undefined.
Here is the code:

In the code below the preFilladmin function creates a JavaScript error after leaving the admin_uid field

This is the first time i'm really using javascript objects (well the first time i've written my own one) so the problem is probably a very simple one...
I've got this:

When i change the country from the dropdown box i get an error "hometown.setCities is not a function" but the thing is that i can call this in other ways eg from the address bar (javascript:hometown.setCities()) and it works perfectly.

In my project we have made many applications which consist of jQuery 1.3.2 and 1.4.2 code. Now we are planning to upgrade to jQuery 1.5.1. Can anyone tell whether 1.5.1 or its previous versions are backwards compatible with 1.3.2 and 1.4.2? It would also be great if anyone could point me to some discrete source (links). I have tried a lot while googling but found nothing much, just that 1.5.1 supports IE9.

This works fine with 1.4.2, but with 1.4.3 I get an error in jquery-1.4.3.js using Firebug: handler is undefined Line 1797
This happens on line 2 of the code
To me it looks as if the wrong .load method is being called, from the jQuery docs:[url]
Note: The event handling suite also has a method named .load(). Which one is fired depends on the set of arguments passed.
I think the event .load method is being called because line 1797 in jquery-1.4.3.js
if ( handler.handler ) {and comments around it talk about binding events to objects etc.
Can anyone confirm this is the case, or something else is causing the error with 1.4.3

I have simple function that I call from an alert box
alert(testScore);
It works fine. Unfortunately, I do not like the sound and Exclamation
point icon that appears. I'd like a nice message box like VBA message
box #64 to appear. I know hardly anything at all about VB or VBA.
But, I do know you can call a VB function from Javascript. How? Is it
possible to get my testScores to appear from the VB function? Is it
hard? Where do I start looking?
I have a page with an iframe. The page defines some JavaScript functions in the head part. How can I access these functions from the iframe? In Firefox I can use parent.myFunction() but it doesn't work in IE.
